Investigating The Size-Dependent Static And Dynamic Behavior Of Circular Micro-Plates Subjected To Capillary Force

Simon Nessim Henein, Ilan Vardi, Mohammad Hussein Kahrobaiyan

The size-dependent static deflection, pull-in instability and resonant frequency of a circular microplate under capillary force have been studied using modified couple stress elasticity theory. SiZe-dependency is a phenomenon in which the normalized quanti ...

A Wideband MDLL with Jitter Reduction Scheme for Forwarded Clock Serial Links in 40 nm CMOS

Seyed Armin Tajalli, Yusuf Leblebici, Kiarash Gharibdoust

This paper presents the design and implementation of a multiplying delay-locked loop (MDLL) in 40 nm bulk CMOS process, which can be used as clock and data recovery (CDR) unit in source-synchronous wire-line communications. The MDLL multiplies the referenc ...

Wearable, multi-parametric wireless system-in-patch for hydration level monitoring

Mihai Adrian Ionescu, Hoël Maxime Guérin

Wearable system based on an in-situ four-probe impedance measurement at different signal frequencies for the topical monitoring of at least one physiological parameter reflecting the hydration status such as skin conductivity, ion concentration in sweat or ...

System for the remote monitoring of the hydration status of a living being

Mihai Adrian Ionescu, Hoël Maxime Guérin

System for monitoring the hydration status of a living being by exploiting the modulation of backscattered RF electromagnetic waves from a wearable patched placed on the skin, said system comprising: a RF-tag adapted to be directly or indirectly fixed to t ...

Sub-Nyquist artifacts and sampling moiré effects, Part 2: Spectral-domain analysis

Isaac Amidror

Sampling moiré effects occur due to aliasing (foldover) when a continuous periodic signal g(x) is sampled using a sampling frequency that does not respect the Nyquist condition. However, visible beating artifacts may also occur when g(x) is sampled using s ...

Real-Time Control of Microgrids with Explicit Power Setpoints: Unintentional Islanding

Jean-Yves Le Boudec, Mario Paolone, Lorenzo Enrique Reyes Chamorro, Andrey Bernstein

We propose a method to perform a safe unintentional islanding maneuver of microgrids. The method is derived in the context of a framework for the real-time control of microgrids, called Commelec, recently proposed by the authors. The framework uses a hiera ...

Standing wave integrated Fourier transform spectrometer for imaging spectrometry in the near infrared

Hans Peter Herzig, Gaël David Osowiecki, Irène Antoinette Philipoussis, Mohammadreza Madi, Toralf Scharf

We show the miniaturization and parallelization of a scanning standing wave spectrometer with a long term goal of creating a compact imaging spectrometer. In our standing wave integrated Fourier transform spectrometer, light is injected with micro-lenses i ...

Parity-Time Acoustic Metamaterials and Unidirectional Invisible Sensors

Romain Christophe Rémy Fleury

We theoretically and experimentally investigate the unique scattering properties of parity-time acoustic systems. We observe acoustic invisibility of airborne sound at audible frequencies in a parity-time symmetric meta-molecule made of perfectly balanced ...

Markers for risk to develop atrial fibrillation based on a new electrocardiographic tool

Atrial fibrillation (AF) is the most important trigger for heart failure and stroke. Reliable methods for predicting AF are lacking and ECG analysis could improve this process. P-wave characteristics in the ECG are an important source of information in the ...

Time-frequency analysis of long fiber Bragg gratings with low reflectivity

Luc Thévenaz, Sang Hoon Chin

A new technique to investigate the spatial distribution of the reflection spectrum along fabricated long weak fiber Bragg gratings (FBG) is experimentally demonstrated, together with its potential applications for distributed fiber sensing and broadband si ...
